Sure I'll give it a try on the next week.
May I ask you why the fix concerns the WndProc only?
I thought that if a UNICODE API function is called, regardles the control is 
ANSI or UNICODE, it still should accept WIDE strings in the INPUT parameters 
and return WIDE strings in the OUTPUT ones. What I see in 0.9.40 is that 
UNICODE control treat INPUT as ANSI even if UNICODE function is called.
Well, even if control has ANSI WndProc, it should convert UNICODE->ANSI for 
the parameter I passed to SetWindowTextW. Will the patch fix this problem?
